C++ C++;:Boost:需要目录导航逻辑的帮助吗
因此,我试图更改我的目录以保存文件,然后更改回以前所在的目录 基本上:C++ C++;:Boost:需要目录导航逻辑的帮助吗,c++,boost,boost-filesystem,C++,Boost,Boost Filesystem,因此,我试图更改我的目录以保存文件,然后更改回以前所在的目录 基本上: cd folder_name <save file> cd ../ cd文件夹\u名称 cd/ 以下是我目前掌握的代码: void save_to_folder(struct fann * network, const char * save_name) { boost::filesystem::path config_folder(Config::CONFIG_FOLDER_NAME); b
cd folder_name
<save file>
cd ../
cd文件夹\u名称
cd/
以下是我目前掌握的代码:

std::cout根据文档,当前的_路径方法有点危险,因为它可能同时被其他程序修改
因此,从CONFIG_文件夹_名称进行操作可能会更好
能否将更大的路径名传递给fann_save?类似于:
if( !(boost::filesystem::exists(config_folder)))
{
std::cout << "Network Config Directory not found...\n";
std::cout << "Creating folder called " << Config::CONFIG_FOLDER_NAME << "\n";
boost::filesystem::create_directory(config_folder);

fann_save(network, (boost::format("%s/%s") % config_folder % save_name).str().c_str());
boost::filesystem::path up_folder((boost::format("%s/..") % Config::CONFIG_FOLDER_NAME).str());
boost::filesystem::current_path(up_folder);

我认为您可以删除最后一行代码boost::filesystem::current_path(parent_folder);
。每当您输入函数时,您都会将路径设置为要处理的文件夹。我不会将“./”用于父文件夹,而只是“..”。我认为您可以删除最后一行代码boost::filesystem::current_path(parent_folder);
